Charter Appealing NAD Finding About Mobile Speeds

Charter Communications plans to appeal a National Advertising Division finding the cable ISP should drop or modify its "fastest overall speeds" nationwide advertising claim about its Spectrum Mobile service, NAD said Tuesday. NAD said AT&T challenged the ad claim, saying Spectrum Mobile is faster only in certain markets or when connected to Spectrum Wi-Fi. NAD said Charter indicated the NAD decision was based on an archaic view of mobile communications, not accounting for how it commonly integrates Wi-Fi and cellular communications. The appeal will go to the Better Business Bureau's National Advertising Review Board. Charter didn't comment.
